BRAKE-OPERATING MECHANISM.

appiieation inea september is, 192e. seriai No. 134,962.

This invention relates to brakes and is illustrated as embodied in novel operating mechanism for a front wheel automobile brake. An object of the invention is'to provide,'in a brake control supported at one end on the chassis frame, for unusualmovement of the frame due to the action of the vehicle springs, by providing, on the frame a pivotal support permitting the shifting of a joint slidably supporting the inner end of a brakeapplying shaft.

The above and other objects and features of the invention, including various novel and desirable details of construction, will be apparent from the following description of one illustrative embodiment shown in the accompanying drawing, in whichi Figure 1 is a vertical section through one front brake and through associated parts, showing the brake control in rear elevation;

Figure 2 is a view corresponding to part of Figure 1 but showing the positions of certain of the parts when the vehicle spring is very greatly distorted; and

Figure 3 is a section on the line 3-3 of Figure 1 showing the pivotal mounting for the shaft support on the chassis frame.

In the arrangement illustrated the brake includes a di'um 10 rotatably mounted with a wheel (not shown) on the spindle 12 of a knuckle 14 which is swivelled by a kingpin 16 or the like at one end of the front axle 18. The brake shown includes shoes 20 arranged inside of the drum and applied by means such as a double ycam 22 operated through a suitable universal joint 24 by a brake-applying shaft 26.'and the open side-of the drinn 10 may be closed b v a suitable backing plate 28. The particular brake illustrated is substaiitially'the same as that fully describedv in Pat-v ent No. 1.567,716, granted Bendix Brake Company December 29', 1925, on an applica- Y. Dodge, except that the free ends of the brake shoes are confined laterally by a flange 3() formed on one end of the cam The' present invention relates to the novel means for supporting the' inner end of the shaft 26. Preferably the inner end of this shaft is to be supported on a chassis' member, such as the side member 32 of the vchassis frame supported by the usual vehicle springs on the front axle 18 and on a rear axle (not shown).

The inner end of the shaft 26 is preferably slidably supported in a sleeve 34, to permit axial movement to compensate for distortion of the vehicle springs. rlhe sleeve 34 is arranged-within an outer' liemispherical stamping 36 and an innerhemispherieal stamping A38 embracing a generally spherical support 40 which is preferably formed as an integral extension of a base 42. The hemispherical stampings 36 and 38 are yieldably urged against the opposite sides of the support 40 by ajspring 44 confined between the inner hemispherical stamping 38 and the dia phragm 46 carried onthe end of the -sleeve 34. Sleeve 34 has fianges at its opposite ends to engage stamping 36 and diaphragm 46. j

The base 42 of the above-described slidable and yieldable joint or support for shaft 26 is bolted or riveted or otherwise secured to a dished plateor other support 48 pivotally connected` as for example by a pin 50,

to a stamped bracket 52 which is bolted or Y invention has been described in detail, it is not my intention to limit its scope to that par-I sov ticular embodiment or otherwise than by the' 'I terms of the appended claims.

I claim:

' 1. A support for a brake-applying shaft comprising, in combination. a universal joint including a sleeve for holding the end of-a brake-applying shaft in a manner permitting the shaft to move axially` a bracket adapted to be secured to a chassis frame, and means for pivotally mounting the joint on the bracket.

2. A support for a brake-applying shaft comprising, in combination, a universal joint including a sleeve for holding the end of a brake-applyin g shaft in a manner permitting the shaft tomove axially, a bracket adapted to be secured to a chassiseframe, and means for pivotally mounting the joint on the bracket, for movement about a horizontal axis paralleling the side of the Chassis frame.

` In' testimony whereof., I have hereunto signed my name.
